Ok, I am not sure. I run Postgres as a service, and when my Windows rebooted after a patch, UNLOGGED tables were cleaned... maybe the patch process in Windows messed something up, I don't know.

Windows *does* signal shutdown (and sleep and hibernate and wakeup).
pg_ctl can catch these signals only when running as a service ... it
will not catch any system signals when run as an application.
